COLLAR OR CUFF BUTTON.

SPECIFICATION forming part. of Letters Patent No. 354,521, datedDecember 14, 1886.

Application filed September 30, 1886. Serial No. 215,022. (No model.)

To all whom it may concern.-

Be it known that. I, HENRY H. SUMMA, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Collar, Sleeve, and Cuff Buttons or Studs, ofwhich the following is a specification.

This invention relates to that class of collar or cuff buttonsconsisting of two parts separable from each other, and held together bya spring locking device.

The object of my invent-ion is to make a cheap, simple, and durable aswell as neat and strong button, which may be readily placed in thebuttonhole to hold a collar or cuff in place without danger ofseparating and dropping out and being lost, as well as to be readilyseparated for removal or insertion.

To more fully describe my invention and to enable others to fullyunderstand the same, reference is had to the accompanying drawings, inwhich 7 Figure 1 is a perspective view of the top part of my improvedbutton. Fig. 2 is a perspective view of the bottom part or shoe. Fig. 8is a perspective View of the button, with part of the top broken away,showing the two separable parts locked together. Fig. 4 is a top view ofthe button, showing the flat cross-headinserted through a slot in thebottom of the top part, and standing parallel with said slot, and as itappears before being turned and locked. Fig. 5 is a like View of thebutton, showing the spring pressed in unlocking the shoe. Fig. 6 is adetail view of the cross head.

Similar letters refer to similar parts throughout the several views.

A isthe shoe or bottom plate of the button.

B is the top part. To the shoe is secured the stem a, as usual. Thisstem has a fiat upright cross-head, O, as clearly shown in Figs. 2, 3,and 6. This diet upright crosshead facilitates the insertion of theshank or stem into the buttonhole by placing it in a longitudinal linewith same, and at the same time keeps the shoe in the button-hole whenturned crosswise to it and prevents its dropping out when the top part,B, is removed. The top part, B, is around hollow box, (with a flat,round, or circular bottom,) for the reception of the spring lockingdevice and crosshead of the shank, as well as for receiving the stone orset. In the bottom of the top part is cut a slot, b, for receiving'thecrosshead 0, (see Figs. 4 and 5,) and at its middle, at b, it isenlarged for receiving the round shank a.

D is a spring, preferably made of flat steel bent in a circle, one endof which is secured to the inside face of the wall of the part B, whilethe other end is passed through the wall to the outside and providedwith a push button or knob, d.

d is a lug formed on the spring and placed so as to be a little to oneside of the center of the top part, and on one side of the slot b, andin line with a stop-pin, (Z on the opposite side of the slot. Thestop-pin d serves to limit the turning of the cross-head in onedirection, one end of which abuts against it, as shown in Figs. 3and 5.The opposite end of said cross-head coming in contact with the beveledportion d of the lug forces the spring back until the lug is passed,when the latter snaps behind. it, preventing the cross head from turningback, thus firmly locking the parts together. (See Fig. 3.)

The cross-head may be made so as to have its flat sides wedge-shaped,spreading from the top downward, as shown in Fig. 6, to betterfacilitate its insertion into a stiff buttonhole.

To separate the two parts of the button, it is but necessary to push inthe button or knob d, forcing back the spring D, so as to bring the lugback far enough to be cleared by the cross-head, as shown in Fig.5,'then turning the shoe so as to bring the cross-head in longitudinalline with the slot 1), as shownin Fig. 4, and then lifting off the toppart, B, for removal. The cross'head being new crosswise to thebutton-hole, thus prevents the shoe from dropping out of thebutton-hole, and when turned parallel with it can easily be withdrawn.

What I claim is-- In a collar or sleeve button, the stem A, having itsshank provided with a fiat upright cross-head, O, in combination with atop part, B, provided with a slot, b, in its bottom, said slot beingenlarged in the center at b, the spring D, provided with abutton orknob, d, and a'lug, d, and the stop-pin (i all constructed and operatingsubstantially as herein .shown and described, and for the purpose set.

forth.
